INSTALLATION
Before installation, remove old liquid gasket from mating surface of all liquid gasket applied parts.
1. Install cylinder head gasket.
●Cylinder head gasket to be installed is selected by its thick-
ness through the following procedure.
–When replacing gasket alone
• Install a gasket with same thickness as that of the one
removed.
• Identify the thickness of gasket by the number of cut-outs on
the RH side.
*: Measured with head bolts tightened
• Gasket thickness can be identified at the location shown in
the figure by the numbers of cut-outs before removal.
–When the following parts have been repaired/replaced:
●With cylinder block upper surface and/or crankshaft pin jour-
nal ground
●With cylinder block, pistons, connecting rods, and/or crank-
shaft replaced
a. Set piston at a point close to TDC.
b. Set a dial gauge at the location as shown in the figure. Turning
crankshaft gradually, set the gauge scale to “0” where the piston
protrusion is maximized.
c. Move the dial gauge stand so that the tip of dial gauge can con-
tact the cylinder block. Read the difference.
d. Measure at two locations per cylinder, that is eight locations for four cylinders. Select gasket based on the
maximum protrusion of eight measurements.

side, referring to the dimension shown in the figure.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Using valve guide reamer, perform reaming to the press-fitted
valve guides.
Valve Seat Contact
●Before starting this check, confirm that the dimension of valve
guide and valves are as specified.
●Apply red lead primer on contacting surfaces of valves seat and
of valve face to examine the conditions of contacting surfaces.
●Check that the paint on contacting surfaces is continuous along
the entire circumference.
●If there are abnormal indications, grind the valve and check the
contact again. If abnormal indications still persist, replace valve
seat.
Valve Seat Replacement
●When removing valve seat, replace it with oversized [0.5 mm (0.020 in)] valve seat.
